how many on here have run both dirt or asphalt in different seasons seems we have lost more engines on asphalt since leaving dirt

In my opinion, Pavement is harder on motors in most appications for two reasons :

1) you are always hooked up and "loading" the engine while accelerating. All that torque/shock is sent back up the driveline to the crank ultimately.

2) When you lift, it's the same thing, just backwards. The amount of force while slowing down directed back at the motor is much greater on pavement.

At the upper levels of dirt (Super Lates, Sprints, etc) the cars are hooked up enough that maybe the difference is small. In a street stock or mod, I think pavement is much harder on all driveline parts.
